LBO(Lithium Triborate LiB305) is a newly developed nonlinear optical crystal.It is unique in many aspects,especially its wide transprency range,moderately high nonlinear coupling,high damage threshold and good chemical and mechanical properties.
LBO Crystal Advantages
1. Wide transparency,. High nonlinear coupling, good chemical and mechanical properties
2. Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.
3. High damage threshold(18.9 GW/cm2 for a 1.3ns laser at 1054nm)
4. Wide acceptance angle and small walk-off angle
5. High optical quality (homogeneity≈10-6/cm)
LBO Crystal Applications:
1. High power Nd:YAG and Nd:YLF lasers for R&D, military applications, Frequency-tripling (THG) and Medical, Industrial.

NOTE:
1. LBO has a very low susceptibility to moisture.
2. Users are advised to provide dry conditions for both use and preservation of LBO.
3. WTS can select and design the best crystal for you if parameters of your laser are provided, for example, energy per pulse, pulse width and repetition rate for a pulsed laser, power for a cw laser, laser beam diameter, mode condition, divergence, wavelength tuning range, etc.
4. WTS provides mounts and sealed housing for LBO crystals.
Hollow Retroreflectors are constructed of three first-surface mirrors assembled by a proprietary process into a mutually-orthogonal inside corner. Incident Light is Reflected Back to the Source Hollow Lightweight Design
Double Concave Lenses, Bi-Concave Lenses is like the Plano-Concave lenses in that they are used to produce divergent light. The Bi-Concave is best used when the input beam is converging. 1. Supported by the Zemax Optical Design Package 2. Negative Focal Length 3. Material upon requirement
Dual Wavelengths Waveplate is a multiple waveplate that provide a specitfic retardance at two different wavelengths Operates as λ/2 @ λ1 & as λ/4 @ λ2 Dual Wavelength Operation 532 nm/1064 nm
Pyramid prisms has a base that is connected to a single vertex, not in the same plane as the base, by line segments from each vertex of the base shape.
Yttrium Vanadate (Nd:YVO4) is one of the most efficient laser host crystal currently existing for diode laser-pumped solid-state lasers.
